go swimming in the (sp?) centoes, it was fun and the water is cool, was a nice break from being in the heat all day, we did it after we spent the whole day getting hot and sweaty on atv's and riding the zip lines.

Cenotes. I was going to suggest the same if they have them on the island. It's awesome.
